RAIL-JOINT.

SPECIFICATION forming part of Letters Patent No. 699,903, dated May 13,v1902. Application filed March 3, 1902. V SerialNo. 96,502. (No model.)

To all whom it may concern:

Be it known that 1, JOHN THRAILKILL, a citizen of the United States,residing at Dexter, in the county of Dallas and State of Iowa, haveinvented certain new and useful Improvements in Rail-Joints; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable Others skilled in theart to whichit appertains to make and use the same.

This invention aims to providea rail-joint of novel formation which willpresent a continuous up-bearing surface at the juncture formed betweenthe ends of adjacent rails, the joint being braced against both verticaland lateral stress. I

For a full description of theinvention and the merits thereof, and alsoto acquire a knowledge of the details of construction of the means foreffecting the result, reference is to be had to the followingdescription and drawings hereto attached.

While the essential and characteristic features of the invention aresusceptible of modification, still: the preferred embodiment of theinvention is illustrated in the accompanying drawings, in which- 7Figurel'isa perspective viewof a rail-joint embodying'the invention.Fig. 2 is a transverse section. Fig; 3 is a perspective view. of onemember of the joint. Fig. 4 is a perspective view of the other member ofthe joint. Fig. 5 is an end view of both members of the joint.

Corresponding and like parts are referred to in the followingdescription andindicated in all the views of the drawings by the samereference characters.

The joint comprises the members 1 and 2, which represent the ends of adjacentrailroadrails. The member 1 has spaced extensions 3 in line withside portions of the foot or base anda mortise 4, extended inward for ashort distance from the, extremity, said mortise opening upward throughthe tread of the member and having its side walls slightly upwardlyflared. The foot of the member and each side of the web are cutaway fora short distance from the extremity to form a space to receive theofiset portion 5 of the spliceplate 6, which is bolted against the sideof the joint and firmly attached to a tie.

The member 2 has a longitudinal extension 7 to snugly fit the mortise 4,the sides of said extension being slightly-upwardly diverged to conformto the Hare of the sides of the mortise 4. The foot is cut away' at eachside of the web, as shown at 8, to receive the extensions 3, whichembrace opposite sides of the web and in conjuction with the extension 7prevent lateral movement of the members comprising the joint. Theextension 7, fitting the mortise 4, prevents any vertical play of themembers and insures the formation of a'contiuuous surface for supportingthe walls when passing over the joint, thereby preventing any jar orshock, such as commonly experienced in railways having the adjacent endsof rails abutting simply without anyinterlocking.

When the members are fitted together, a space is provided at each sideof the web and extends equally to the right and to the left is claimedas new isv 1. In a rail-joint, a member having spaced basal extensionsand a longitudinal mortise extended inward from the extremity of therail and opening upward through the treadsurface, and the other memberhaving the foot of the rail cut away at each side of the web to receivethe aforesaid extensions, which embrace the sides of the web, and alongitudinal extension to fitwithin the said mortise, substantially. asset forth.

2. Ina rail-joint, a member having spaced longitudinal extensions, and amortise extended inward from the extremity and having its side wallsupwardly flared, and the mating member having the foot'cut away at eachside of the web to receive the aforesaid spaced extensions andhavingalongitudinal extension with its sides upwardly diverged to snuglyfit the aforesaid mortise, substantially as set I Wings to be attachedto a tie, each of the forth. splice-plates having an offset portion tofit a 3. In a rail-joint, a member having spaced cut-away part of thefoot of the rail member longitudinal extensions and a mortise, theforming the joint, substantially as set forth. 5 mating, member having aportion of the foot In testimony whereof I afiix my signature 15 cutaway upon each side of the web to receive in presence of two witnesses.
